LUBRICATOR.

To all 'whom t may/concern:

Be it known that I, PERRY B. SAMPLE, a' citizen of the United States, and a resident of the city of New York, borough of Brooklyn, county of Kings,and State of New York, have invented a new and Improved Lubricator, of which the following is a full, clear, and exact description. v

This invention relates to oilers, lubricators, and the like'. More particularly the invention relates to a lubricator yspecially designed to inject graphite, powdered soap stone, talcum or other similar lubricating substances to manifolds, crank case, and cylinders of internal combustion motors.

An object of the inventionv is to disclosey the design of a Vlubricator for use in connection with engines, and particularly gas engines, which will effectively handle dryY lubricants, and which may be adjusted to feed said lubricants in regulated quantities to the engine parts to be lubricated.

Another object is to provide a means of regulating the quantity of lubricant into the engine parts, and also means are employed for regulating the rate of flow of lubricant.

It is a further object to `provide a lubricator which will be comparatively simple `in construction and operation, not expensive to build, and which will comprise a mini; mum number of working parts.

With the above and other objectsin view,

the invention has relation to a certain combination and arrangement 0f parts, an eX- ample of which is identified in the following description, designated in the appended claims, and portrayed in the accompanying drawings which show a longitudinal sectional view of thelubricator.

Referring now more in particular to the drawings, the numeral 1 points out a base upon which the lubricator parts are mounted. A threaded boss 2 is made on the base 1, and the base is provided with a shoulder formed on the rim. A cylindrical casing 3 is mounted on the base and used to hold the lubricant which is to be fed to the engine. The base is bored out at 4, and a ring plug 5 fitted into the base at the upper end of the bore.

A cover cap 6 is fitted on the top end of the casing and forms an inclosed `lubricator cup. This cap is provided withla filler plug lubricant.

7 through which the lubricator is filled. 'The plug'will have an air inlet or vent to insure equalization of air pressure. l

Application .led June 6, 1919.- Serial No.' 302,223.

A lhreaded'plug 8 is screwed into a hole formed in the cap 6. This plug is provided with air inlets 9. A valve seat 10 is formed on the inner side of the cap 6 by counterboring the hole which mounts the plug 8. A` valve 1l is mounted to close, or approximately closeagainst the valve seat.. Thevalve depends from a soft and yieldable spring 12 vwhich is attached to an adjusting screw 13. The adjusting screw is threaded into the'plug 8 and is fitted with a lock nut 14: employed to hold the adjusting screw in i fixed position.

A lubricant feed pipe-16 is disposed lon-A gitudinally within the lubricator cup with the lower open end inserted in the ring plug 5 to form a close fitting joint and to connect with the bore l. The upper end of the feed pipe may be iiared out to encompass the Vvalve and valve seat. The upper end of the tube lwill 'closely fit the` surface yof the cap to form an air-'tight joint. The feed ipe joins with a downwardly directed tubuai' extension 17 4which' is open at the b0t-' tom and which terminates just` above the surface ofthe base. AThus the open lower end of the tubular extension is spaced from` the'surface of the base. Y f.

An injector tube isemployed to pass airunder atmospheric Vpressure intothe lubricator cup for picking up the dry or iake This consists oftheftube 18 inserted in the tubular extension 17 and open at the lower end. The lower open end is slightly spaced above the open end of the tubular member 17. A valve 20 is provided on the cap, and the injector tube connects with this valve. The valve may be closed or' opened to control the airflow or injection to the tubular extension and feed pipe.

The lubricator is attached to an engine by screwing the threaded boss into a tapped hole made in the intake manifold, Acrank case, or other engine parts. It is often desirable to pass small and-regulated quantities of dry lubricant such asgraphite 'to the cylinder walls or other parts. This may be effected by utilizing thel suction or intake @stroke of the motor to carry in particles of lubricant. The lubricator casing or cap is filled and proper regulation of the valves effeared. ,Thann-iene wiuefbankepamurid the lower open tube 17 ,and closethetube by partly working up into it.

The suction stroke of the engine will in! duce a Vacuum through-the feed `pipe,tubu` lar extension and the air injector tube. ,The dry and flake lubricant isbanked within the open mouth of the tube 17 directly beneath the openend of the air injectortu'be. On each suction impulse of the engine, the air injector tube will project a stream of air downwardly against the'banked lubricant. rlhis causes the lubricantgparticles to flutter and become suspendedin the air Within the tubular extension. The particles in suspension are rapidly ,drawn upwardlythrough the V tube 17 and downwardly,through the feedl pipe and passed; from the lubricator to the engine.

V,The valve 20 .will be nel-yadjusteditoregniet@ the quantity `of air taken in: t0 ,break up .alldmlift the Vlublrmntparticlesintosus- Peneolt .The more Pair admitted through this yalre thelarger the quantity of lubricant t0 .be fed Lto .the engine, thusthecquan- A tity of feed v is; regulated` Vbythe yalye The valve 11 v'may be adjustedjto admit more or less air through the Valige 11142 deuring theoperationfof the engine tobe lubricated. `Byadjliisting the Valve nearly closed, a very-small; Iamount of air flows v through the passa-ges,9Jintoxthefeed pipe. AIn this way the downward rate of movementgoffair in the feed pipe is regulated to flow Very slow `in velocity. If the valve vis openfulh maximum rateof airflowor Vvelocity is `attained. Thus the rateofflow of lubricant iseffectedthrough 'properadjustment of this Valve 11.'.

Thisitype of lubricator may berused to good effect where dry lubricant is in use. Its regulating means provide adequate-contrjol -of amount of: lubricant; to `be `issued-to the bearin-gs,`,andy the speed or.,` rateat which itwill be issued. Y
